Generating interest income on idle cash balances kept in retail brokers - a theory

For brokers that allow you to buy bonds, its very natural to buy it and use it as collateral. The tricky part is when you have a broker that does not allow bond buying and perhaps even futures buying (I have a couple like these). It feels unnatural to go long something in another account, in order to 'earn' interest in the first account but its the right thing to do. I never read this sort of advice before perhaps because its a bit unusual but i think its right. its all one big account called 'your networth' anyway.

Well, a few things here. Say you have broker XYZ and they don't allow access to cash treasuries. You can buy the treasuries direct and transfer them to broker XYZ to fund your account. Serves the same purpose. You don't need to be able to trade them because you are using them as a fixed income investment. Besides they are highly illiquid once you get them. BTW, the other benefit to this appeared when MF Global blew up. Anyone who kept their money in their futures account as cash lost it. However if you bought treasuries and kept them at the FCM, your money was protected. The treasuries are in YOUR name and cannot be liquidated to meet the obligations of the FCM.

Good stuff. Unfortunately, us non-US folks don't have access to treasury direct
 
Consider me fairly ignorant on the topic of bonds (because I am). Suppose you use this bond strategy for income but while you are holding them, they decline dramatically. What is your strategy in this case? Does buying bond futures allow you to hold the bonds until maturity?
Buying and hold a 10y bond to maturity is very similar to rolling a 5y future over and over again. The 10y has more duration risk at first but since that declines over time (as it gets closer to maturity) the average duration will be similar to the 5y future. Point is its a very low risk strategy, I havent looked at the numbers but I suspect it makes money at year end like 80%+ of the time. If the Fed goes 1994, sure you will lose but as I said, that is offset by the fact that you now get to invest at higher rates and hence, that makes it less likely you will lose going forward

Also, the risk that you take buying the futures has to be weighted against the risk of doing nothing. Doing nothing costs 1.5-2% per year (inflation), so if doing something on average will help offset that. its a decent idea
